crankcase and pcv are the same thing pretty much

factory crankcase/pcv systmems vent back into the intake.

mine doesn’t, it vents right to the ground, no catch can, just two hoses tee’d into one.

onbe from the oil filter breather housing or w/e it is and one from my valve-cover.

a catchcan collects blowby.

you really should collect the oil/water vapor. if you go to lvd youre oiling down the track the whole pass.
